The CozIR®-LP is an ultra-low-power, low profile ambient air CO2 sensor. It can run on a compact battery, removing the need for larger batteries and super-capacitors. That represents half the power consumption of the best-in-class competing CO2 sensors. 

At less than 8mm tall it's 85% smaller than the CozIR®-A Ambient sensor, which equates to a 40% savings in space.

The CozIR®-LP, now has a new low power compatible companion the CozIR®-LP2 5000ppm CO2 Sensor, as well as the CozIR®-Blink Sensor which encompasses extreme power conservation.


  • Ultra-Low Power Consumption
